For BLDC motor, square wave and sine wave are two different motor drive solutions, with its own advantages and disadvantages.Square wave drive is widely used. Its advantages are of high torque, simple control, low cost. But its disadvantages are of torque fluctuation and large noise.Due to complex algorithm, sine wave drive becomes one technical bottleneck many companies are trying their best to break through. Its advantages are of smooth torque, high efficiency and low noise. However its disadvantages are of&...

BLDC motor, comparing to traditional brush DC motor, adopts electronic control to switch current direction, replacing mechanical carbon brush. Accordingly its structure has not carbon brush for switching current direction. thereby this kind of electronic control eliminates mechanical abrasion, lower noise, reduce vibration, reduce fever, and doesn't bring spark. The performance of BLDC motor is safer and more reliable. It has longer life time and is easy to maintain. It is more efficient to save power. Extensive applica...
